Configuring Quality of Service
Quality of Service (QoS) is a set of low-level networking protocols giving higher priority to
more important data flows while ensuring that the less important ones do not fail. QoS is an
essential technology for organizations rolling out a new generation of network applications
such as real-time voice communications and high-quality video delivery.
In the Nextiva edge devices, the two available QoS flavors are Type of Service (ToS) and
Differentiated Service Code Points (DSCP).
For QoS to be taken into account, the network infrastructure equipment (switches and
routers) must support one of these protocols. If any of these devices does not support QoS,
the QoS data will simply be processed as traditional non-QoS data. Furthermore, all Nextiva
edge devices on a network must support the same QoS protocol (or no protocols at all).
You can set a priority flag to three data types coming out of an edge device: video, audio,
and control. A QoS-enabled switch (or router) uses this flag to determine how the current
data compares to what is currently going through it.
The QoS values are in the Advanced > Quality of Service menu.
Using the Web Interface
The S2800e camera provides a web interface for viewing live video and controlling the PTZ
functions. Microsoft Internet Explorer 6.0 or later is required.
To access the web interface, you must change the DIP switch configuration from the SW1
and SW2 blocks on the camera drive board. In that configuration, the camera cannot be
reached by Nextiva Control Center or Nextiva Review anymore; to reset the switches to
their initial configuration, see page 41.
The first time you access the web interface or after updating your camera from a previous
firmware release, you need to install or upgrade an ActiveX control for live viewing.
To prepare the S2800e for the web interface:
1. Power off the camera.
2. Remove the camera drive from the enclosure.
3. Set the 16 DIP switches from the SW1 and SW2 blocks to 0 on the drive board.
Note: Do not use the configuration pages of the web interface to change the parameters
of the S2800e because they will be overwritten by Nextiva Control Center.
